Embodiment Construction

[0019] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] figure 1 It is a structural diagram of a microwave plasma ignition internal combustion engine combustion system provided in an embodiment of the present invention. The microwave plasma ignition internal combustion engine combustion system includes a microwave ignition device and a combustion chamber, and the microwave ignition device feeds preset frequency microwave pulses, which are used to break down and ignite the combustible gas mixture in the combustion chamber, specifically, the microwave pulses resonate in the combustion chamber to generate a large volume of plasma and reactive radicals, thereby igniting the combustion Indoor combustible gas mixture. Wherei...

Abstract

The invention provides a microwave plasma ignition combustion system of an internal combustion engine. The microwave plasma ignition combustion system comprises a microwave ignition device and a combustion chamber, wherein the microwave ignition device feeds microwave pulse with preset frequency into the combustion chamber; the microwave pulse is used for puncturing and igniting combustible mixed gas in the combustion chamber. The microwave plasma ignition combustion system provided by the invention has the advantages that since the microwave pulse with preset frequency is fed into the combustion chamber, the resonance effect is realized in the combustion chamber, and a strong-current magnetic field is generated, so that the combustible mixed gas in the combustion chamber is punctured and ignited, further the lean burn limit of the engine is expanded, the lean burn capability of the engine is improved and stable lean burning is realized.

Description

technical field [0001] The invention relates to the field of engines, in particular to a microwave plasma ignition internal combustion engine combustion system. Background technique [0002] A basic part of the engine is the combustion chamber that converts the chemical energy of the fuel into mechanical energy. The ignition of the fuel in the combustion chamber depends on several factors: oil and gas temperature, type of igniter, ignition energy, fuel-air ratio, ignition energy input point and The degree of automation with which the fuel is delivered from the injector, the combustion chamber requires an igniter to trigger the combustion process, a well known igniter commonly used in automobile and aircraft engines is the spark plug ignition system, which generates a high voltage pulse to the spark plug Above, a transient high electric field is generated between the two electrodes of the spark plug. This high electric field causes the breakdown or discharge of the oil-air mi...
